IMPROVEMENT IN BAKING-DISHES.

To all whom it may concern:

I, BARZILLA HARRINGTON, of China, in the county of Kennebec, State of Maine, have invented a certain new and useful Baking-Dish, of which the following is a specification:

The Nature and Object of the Invention.

Description of the Drawing.

Figure 1 is a plan of my dish. Fig. 2 is a vertical section of the same.

General Description.

My dish may be constructed of any shape and size. The inner and outer walls at e are to be made of any suitable metal and fastened by rivets or closed joints. The interior between these walls is to be filled with gypsum, clay, or any suitable non-conductin g material. The cover B is constructed in the same manner as the dish itself, 0 and I) being of metal and the filling H of gypsum or clay.

This baking-dish has a great advantage over others, as it will not allow the heat of the oven to come in contact with the contents, except gradually, and when the contents once become heated they will remain so a long time; thus the baking will be gradual. This dish will not lose its nou-conductin g power by use, as in case of the ordinary earthen dish. An

earthen dish, after being used a few times, be-

comes saturated and loses its non-conducting power; again, as earthenware is porous, it cools rapidly by evaporation. My dish cannot become saturated hence its efficiency.

I claim as my invention- A baking-dish, consisting of metallic double walls, filled in with gypsum, clay, or some similar nonconducting material, substantially as described, and for the purpose set forth.
